...so shared by the inverse CDF method. See cimat.mx/~src/prope08/randomgauss.pdf . This can be alleviated by using a uniform RNG which has non zero probability to yield a floating point number very close to zero. Most RNG do not, since they generate a (typically 64 bit) integer which is then mapped to...

...2 effectively sets the initial values for the array: a[1] = 70 (close to 72, the ASCII code for the character 'H'), a[2] = 100 (close to 101 or 'e'), a[3] = 30 (close to 32, the code for space) and a[4] = 10 (newline). The loop works by adding 7, 10, 3, and 1, to cells a[1], a[2], a[3] and a...
